Dye Penetrant Inspection (DPI)

Dye Penetrant Inspection (DPI)

Also called Liquid Penetrant Inspection (LPI) or Penetrant Testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials, but for inspection of ferrous components magnetic-particle inspection is preferred for its subsurface detection capability. LPI is used to detect casting and forging defects, cracks, and leaks in new products, and fatigue cracks on in-service component. 

Dye Penetrant can be used on :

– Aluminum & Brass
– Carbides & Cast iron
– Ceramics & Copper
– Magnesium & Stellite
– Steel
– and all non magnetic material
